摘要：

The effects of the partial pressure of oxygen and temperature on the oxygen reduction on a submerged gold electrode in a lithium carbonate melt were investigated using cyclic voltammetry and impedance analysis. The values for the mass-transfer parameters, D(o)1/2C(o), obtained from cyclic voltammetry and impedance analysis were in good agreement. The reaction orders for oxygen at 800-degrees-C were calculated to be about 0.3 for the exchange current density and 0.5 for the product D(o)1/2C(o); these values are consistent with the mechanism proposed in the literature for oxygen reduction in Li2CO3 melt.
